Spring exercise system and method of exercising

ABSTRACT

A spring exercise system and method of exercising that allows a user to perform a full body, low-impact style of exercise. The system utilizes a non-fixed extension spring that stretches and generates resistance when pulling and pressing forces are applied. The extension spring or springs are stretchable between multiple types of interchangeable grasp handles which may include any combination of a resilient loop handle with or without double “D” rings, a single rigid handle, and/or a resilient double loop handle. The spring may have a swiveling link or other mechanism/structure that joins the free ends of the spring to the grasp handles allowing a 360° rotation. The grasp handles are used with combinations of hands and feet, arms and legs to generate an extension of resistance that stretches, strengthens and tones muscles, enhances flexibility, core strength, joint stability, and muscle balance.

CROSS REFERENCE OF RELATED APPLICATIONS

This application claims the benefits of U.S. provisional application No. 62/976,180, filed Feb. 13, 2020 and entitled SPRING EXERCISE APPARATUS AND TECHNIQUES FOR USING SAME, which provisional application is incorporated by reference herein in its entirety.

FIELD OF THE INVENTION

The present invention relates generally to a spring exercise apparatus and method that can be applied across multiple exercise systems including but not limited to Pilates, yoga, ballet, barre, and multiple exercise and Pilates apparatus. Moreover, the present invention relates to a spring exercise apparatus and method that can be applied across multiple exercise systems including but not limited to Pilates, yoga, ballet, barre, in the water and multiple exercise and Pilates apparatus. It is a low-impact system of exercise that utilizes a non-fixed spring, or springs with multiple resistance levels that extends, and is stretchable between multiple types of interchangeable grasp handles that are graspable and loops that can encircle or wrap around with different combinations of the arms, legs, hands and feet. Whereby the spring generates an extension of resistance that strengthens all muscle groups, enhances flexibility, stabilizes and strengthens the joints, while enhancing mobility and range of motion, emphasizing proper postural alignment, core strength, and muscle balance. The spring exercise system can be used for any low-impact exercise system including but not limited to those referenced above.

BACKGROUND OF THE INVENTION

The following background information may present examples of specific aspects of the prior art (e.g., without limitation, approaches, facts, or common wisdom) that, while expected to be helpful to further educate the reader as to additional aspects of the prior art, is not to be construed as limiting the present invention, or any embodiments thereof, to anything stated or implied therein or inferred thereupon.

Typically, Pilates is a method of exercise that consists of low-impact flexibility and muscular strength and endurance movements. Pilates emphasizes proper postural alignment, core strength and muscle balance. Pilates is named for its creator, Joseph Pilates, who developed the exercises and apparatus in the late 19^(th) and early 20^(th) centuries. A Pilates routine generally includes exercises and apparatus that promote core strength and stability, muscle control, and endurance, including exercises that stress proper posture and movement patterns and balanced flexibility and strength. It can also be helpful in training for sports or in physical rehabilitation.

Generally, exercise equipment is used for fitness and medical reasons to burn off undesired calories, to improve cardiovascular ability, to tone or strengthen muscles, or to improve flexibility, balance, posture, etc. No matter what the desired end goal of a user of exercise equipment may be, almost all types of exercise equipment aid the user to achieve his or her desired goal by exerting some form of adequate and effective resistance against repeated bodily movements of the user. Often, the exercise devices utilize elastic resistance members such as coil springs. A hook is often used to connect each of the two ends of the coil spring (or generally a force resisting mechanism) between a movable and a fixed location on the exercise equipment.

This is to say that none of the above have incorporated a spring loaded device such as what we are presenting here that can be implemented Hand-to-Hand, Foot-to-Foot, Hand-to-Foot or limb-to limb and as we have explored the applications of this device, now referred to as CoreSpring™, we have discovered that it answers a deep need in the Pilates, fitness and even the rehabilitative communities for spring resistance that is not dependent on and/or limited to or attached to a large, cumbersome apparatus or fixed to a wall, platform or structure of any kind.

It is known in the art that the creation of CoreSpring™ was born out of a need for the use of spring resistance in areas and environments that were not conducive to attaching springs to a fixed structure or apparatus and when the use of the spring was placed in the hands, feet or any combination of the hands and feet with handles, loops or straps made of cloth, leather, fleece or neoprene the immediate activation of crucial, deep, musculoskelatal, postural muscles were identified and enhanced.

This application of the non-fixed or independent spring created a markedly different effect from other so-called props that are employed in Pilates exercises, both on the mat/floor or on the apparatus. Unlike the rubber bands, tubes or balls, hand or ankle weights, or even other Pilates devices such as the Magic Circle™ that employs a spring-like experience with the use of steel bands with pads that enable it to be held by hands, feet or legs, this independent spring is a completely new experience of spring resistance and not just a prop.

Other proposals have involved Pilates exercise techniques and equipment. The problem with these exercises is that the springs are fixed to a machine, they are not independently held by the hands and feet of the user. Also, only one type of grasp handle is used. Even though the above cited Pilates exercise techniques and equipment meets some of the needs of the market, a Spring exercise system and method of exercising that provides a low-impact system of exercise that utilizes a non-fixed spring that extends, and is stretchable between two interchangeable grasp handles or loops that are graspable with different combinations of the hands and feet, arms and legs so as to generate an extension of resistance that strengthens the smaller, deep stabilizing and long muscles, enhances flexibility, stabilizes and strengthens the joints, while enhancing mobility and range of motion, and emphasizes proper postural alignment, core strength, and muscle balance is still desired.

SUMMARY

Illustrative embodiments of the disclosure are generally directed to a spring exercise system and method of exercising which allows a user to perform a low-impact system of exercise that utilizes a non-fixed spring with multiple resistance levels that extends, and is stretchable between multiple interchangeable grasp handles and loops that are graspable with different combinations of the hands, feet, arms, ankles and legs; whereby the spring generates an extension of resistance that strengthens the small and long muscles, enhances flexibility, and emphasizes proper postural alignment, core strength, and muscle balance.

The system utilizes a non-fixed extension spring that stretches when a pulling or pressing force is applied, generating varying levels of resistance, and thereby developing the long muscles, core, and back of the body. The extension spring is stretchable between multiple types of interchangeable grasp handles and loops. The grasp handles may include any combination of a resilient loop handle with double D rings, a single rigid handle, and a resilient double loop handle. The spring may have a swiveling link or other mechanism joining the free ends of the spring to the grasp handles that allows a 360° rotation and facilitating and enabling that the body has a 3-dimensional experience of spring resistance. The grasp handles are able to be grasped with different combinations of the hands and feet, so as to generate an extension of resistance that strengthens the long muscles, enhances flexibility, and emphasizes proper postural alignment, core strength, and muscle balance. In this manner, different styles of exercise are possible, including but not limited to Pilates exercise.

Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification, are simply exemplary embodiments of the inventive concepts defined in the appended claims. Specific dimensions and other physical characteristics relating to the embodiments disclosed herein are therefore not to be considered as limiting, unless the claims expressly state otherwise.

A spring exercise system 100 and method 3400 of exercising is referenced in FIGS. 1-34 . The spring exercise system 100 comprises a spring 102 having one or more resistances efficacious for effective low-impact training, which can include, but is not limited to, Pilates exercises. The exercise system 100 provides a user with the capacity to change grasp handles types, and levels of spring resistance, so as to customize a unique exercise routine, which can be Pilates-style. Though, other types of exercise routines known to be low-impact and work the long muscles may also be used, such as yoga, Barre, ballet center work, as well as Pilates and other apparatus.

The spring 102, which serves as the primary resistance mechanism, is independent, and thereby not attached to exercise machinery or other stationary fixture. The grasp handles 108 a-b, 202 a-b, 302 a-b on the ends of the spring 102 are interchangeable, so as to accommodate different styles of exercise, and comfort levels for the user. The grasp handles also accommodate the hands, feet, ankles, legs, wrists, arms, fingers, and stationary objects, so as to enable myriad permutations of exercise techniques, exercises and positions. A swiveling connector may or may not attach the free ends of the spring to the grasp handles. The connector mechanism enables the grasp handles/loops to rotate up to 360°, which further increases the types and difficulty levels of exercises and range of motion that can be accomplished.

As referenced in FIG. 1 , the spring 102 comprises an extension spring. The extension spring is configured to absorb and store energy, as well as create resistance with a pulling or pressing force. The spring 102 is also unique in being a non-fixed spring 102. This means that the spring is not anchored to exercise equipment or otherwise. The spring 102 is free to move to any point that the user desires. In one embodiment, multiple users can use a single spring, or multiple springs in tandem to exercise. In yet another embodiment a single user may use multiple springs with multiple loops or handles. In one non-limiting embodiment, the spring 102 comprises a metal material. The material of the spring may be, in one instance, a nickel-plated metal alloy, such as hard carbon or stainless steel. In one non-limiting embodiment, the spring 102 comprises a plastic or engineered plastic material.

In some embodiments, the spring 102 includes a central coiled body, and a pair of opposing free ends 104 a, 104 b. The free ends 104 a-b may terminate at a hook or a loop. The spring 102 has a central body section that is coiled to produce resistance when stretched, or pulled or pressed during exercise. The tightness of the coil and the material of the spring are determinative of the resistance provided by the spring 102. Thus, the spring 102 generates resistance to a pulling or pressing force when stretched. The resistance generated by the spring 102 generates an extension of resistance. Different levels of resistance in the spring may be used, depending on the requirements of the user.

For example, in one embodiment, the spring 102 is configured with a hard resistance level. In another embodiment, the spring 102 is configured with a medium resistance. In yet another embodiment, the spring 102 is configured with a soft resistance. Each resistance level supports a load while being stretched. Variation of resistance can also be achieved by adjusting the loop or grasp handle from shorter to longer, for example.

It is significant to note that the fixed spring defines, and is the common denominator, of Pilates apparatus—not the shape or form of the exercise machine. This is because such a spring-based concept has been employed with the Pilates method-based innovations and machines. In the prior art, whether one is lying down, sitting, kneeling, or standing the spring is fixed and applied directly (i.e. the trapeze table, et al) or indirectly (i.e. the Reformer). However, the present invention employs the spring 102 independently held or maneuvered by the extremities (hands and feet) that works the whole body for activating and orchestrating the core, torso, joint muscles, etc.

Those skilled in the art will recognize that the exercise motions of most upper-body exercises while isolating the hands, wrist, forearm, bicep and triceps allowing isolation of primary muscle groups of the chest, back and shoulders. Furthermore, the system provides comparable exercise benefit requiring approximately half of the weight or resistance the user would normally use in a given exercise. This in turn decreases the pressure and torque on joints, tendons and ligaments and reduces the risk of injury.

Looking now at FIGS. 1-3 , the system 100 includes a pair of grasp handles that attach to the free ends 104 a, 104 b of the spring 102. The grasp handle provides the structural means for the user to secure the spring from its ends, and stretch the spring 102, so as to achieve a 3-dimensional experience and the extension spring (See FIGS. 4-33 ). The grasp handles are configured to enable the hands, wrists, arms, the feet, and/or ankles. The grasp handles allow the spring 102 to be independently held by the extremities (hands and feet) that works the whole body. Suitable materials for the grasp handles may include, without limitation, leather, fleece, neoprene, and cloth.

As illustrated in the various exercise permutations possible with the system shown in FIGS. 4-33 , the grasp handles are grasped or encircled by the hands and the feet to enable extension and retraction of the arms and legs for exercise of the intrinsic core stabilizers and long muscles. The grasp handles are interchangeable, and include three different and unique styles for optimal function during movement and exercises. Each grasp handle 108 a-b, 202 a-b, 302 a-b supports a different exercise system 100, 200, 300, respectively. And two different handles or loops can be used on each end 104 a-b of the spring 102, in any combination of handles or loops. This helps achieve the objective of interchanging multiple, different handles or loops 108 a-b, 202 a-b, 302 a-b on the ends of the spring 102.

In one possible embodiment of the exercise system 100 FIG. 1 shows the handles 108 a, 108 b are resilient loop handles that forms a loop through which the fingers of the hand or the foot can pass through. The resilient loop handle may simply be a loop of a resilient neoprene, cloth or leather that is versatile enough to be used by the hand or arm, or allow the foot or leg to pass through. Thus, as illustrated in FIGS. 4A-4B, the user inserts both hands and arms to pass through the grasp handles/loops 108 a-b while performing a Fundamental Stretch position 400, where the hands are moving a first resilient loop handle 108 a, and one is passing through a second resilient loop handle 108 b. This allows the user to extend the arms and legs to generate an extension of resistance through the zone from the extremities. Furthermore, in the Fundamental Stretch position 400, the user can lie supine, and extend and retract the spring 102.

However, as FIG. 5A references, the user can also stand straight up in a fundamental Salutation position 500 a to stretch the spring laterally while grasping the loops 108 a-b. This allows the user to stretch the spring 102 and generate resistance in the spring 102. And as shown in FIG. 5B, the user can also bend at the waist in the Yoga Triangle Prep position 500 b while stretching the spring 102 with the arms. These unique stretching positions 500 a-b create a Novel exercise routine that allows the user to have a secure grasp while stretching the spring 102 to the desired length to generate the optimal extension of resistance. In each position 500 a, 500 b, the upper body core, shoulder girdle and the long muscles of the arm are being worked.

In another embodiment, an exercise system 200 utilizes a pair of loops 202 a, 202 b. The resilient loop, rotatably attaches to each end 104 a, 104 b of the spring 102 (See FIG. 2 ). The single loop includes a grasp bar 204, which can be grasped by the user, and is connected to the free ends of the spring 102 through a pair of resilient straps 206 a, 206 b.

FIGS. 6A and 6B illustrate use of the loops 202 a-b where the user works on an exercise mat in a Pilates Star Position 600 a with one hand and one foot on the mat and the opposing hand and foot projecting upwardly while stretching the spring with the arms. FIG. 6B reference a Star Twist position 600 b in which the user is in a pike position with both feet and one hand flat on the mat, and stretching the spring with the arms, shoulder and legs.

In another embodiment of the exercise system 300, the loop 302 a, 302 b is a resilient double loop handle, which enables the user to securely utilize each end 104 a, 104 b of the spring 102 (See FIG. 3 ). The resilient double loop handle comprises an inner loop 304 a and an outer loop 304 b. The inner loop 304 a is operable to enable grasping by the hand. The outer loop 304 b can be wrapped around the wrist, foot or leg. In some embodiments, the outer loop 304 b of the resilient double loop handle 302 a-b has a greater resilience than the inner loop.

Looking ahead to FIGS. 12A-12C, the resilient double loop handle is grasped by the user while lying on Pilates Reformer. FIG. 12A references a Pilates Reformer Footwork—Basic Length—Slack position 1200 a with the user passing the hands, palms through the outer loop 304 b, and the thumbs through the inner loop 304 a. The user's arms and legs are retracted and relaxed in this position 1200 a. Continuing, FIG. 12B illustrates a Pilates Reformer Footwork—Basic Length—Stretch position 1200 b with the user extending the arms and legs to create tension on the spring 102. And FIG. 12C shows a Pilates Reformer Footwork—Basic Lateral—Stretch position 1200 c with the user laterally extending the right leg to create tension thereon. The double loops 302 a-b in this configuration allows the hands and the foot to pass through the inner loops for more effective control of the spring 102.

In some embodiments, the system 100 may include a pair of swiveling connectors 106 a, 106 b that are disposed at each of the free ends 104 a, 104 b of the spring 102. The swiveling connectors 106 a-b are configured to connect to the grasp handles/loops 108 a-b, 202 a-b, 302 a-b to the free ends 104 a-b of the spring 102. This may utilize a swiveling linkage, as is known in the art. The swiveling connectors 106 a-b provide a unique nexus that allows the grasp handles/loops 108 a-b, 202 a-b, 302 a-b to rotate up to 360°, relative to the spring 102. This rotation by the grasp handles allows for greater range of motion at the wrist and ankles while stretching the spring. This serves to enhance the exercise routine.

For example, FIG. 6A shows the arm extends laterally to stretch the long muscles. And FIG. 6B shows the left wrist contorted at an angle, but still grasping the grasp handle 202 b, which can rotate to accommodate the wrist and ankle motions. It is significant to note that the illustrated exercises reference the versatility of the exercise system, but represent only a limited number of exercises that are possible by grasping the grasp handles and stretching the spring.

FIG. 34 illustrates a flowchart diagram of an exemplary method 3400 for exercising with the Spring exercise system. The method 3400 may include an initial Step 3402 of grasping, with a hand, a first grasp handle attached to one end of an extension spring. In other embodiments, the foot passes through and engages the first loop. The first loop may include, without limitation, a resilient loop, a single rigid handle, and a resilient double loop. The user grasps the first loop to manipulate one end of the spring.

The method 3400 may further comprise a Step 3404 of abutting, with a foot, a second loop attached to an opposing end of the extension spring. In other embodiments, the hand grabs the second loop. The second loop may include, without limitation, a resilient loop, a single rigid handle, and a resilient double loop. The user grasps the second loop to manipulate the opposing end of the spring. In this manner, both ends of the spring can be stretched to achieve the exercise. The loops are able to be grasped with different combinations of the hands and feet, so as to generate an extension of resistance that strengthens the long muscles, enhances flexibility, and emphasizes proper postural alignment, core strength, and muscle balance.

In some embodiments, a Step 3406 includes extending the arm against the tension of the extension spring. This serves to work the long muscles in the arm. The method 3400 may further utilize a Step 3408 of extending the leg against the tension of the extension spring. This stretching motion strengthens the long muscles in the leg. A Step 3410 includes causing the extension spring to stretch, whereby an extension of resistance is generated. The spring is configured to generate resistance to a pulling or pressing force when stretched. The level of resistance can be changed by the user through selection of different resistance levels of springs. Thus, the spring can be interchanged to achieve a desired resistance level.

In some embodiments, a Step 3412 may include retracting the arm and the leg simultaneously. This motion returns the arms and/or legs to the natural position for another round of stretching. A final Step 3414 includes repeating multiple extensions and retractions of the arm and leg, whereby a low-impact exercise is performed. This repetitive motion strengthens the long muscles, enhances flexibility, and emphasizes proper postural alignment, core strength, and muscle balance. In this manner, different styles of exercises, including Pilates, yoga, barre, etc., are possible.

Although the process-flow diagrams show a specific order of executing the process steps, the order of executing the steps may be changed relative to the order shown in certain embodiments. Also, two or more blocks shown in succession may be executed concurrently or with partial concurrence in some embodiments. Certain steps may also be omitted from the process-flow diagrams for the sake of brevity. In some embodiments, some or all the process steps shown in the process-flow diagrams can be combined into a single process.
